@jim_thompson5910

jim_thompson5910 · Answer

anonymous · Answer

anonymous · Answer

@jim_thompson5910

anonymous · Answer

I think it is D since it is parallel to the base

jim_thompson5910 · Answer

so the 10 is pretty much locked in, so is it 5 or 7?

anonymous · Answer

is it D

jim_thompson5910 · Answer

what makes you say D

anonymous · Answer

because it is parallel to the base and the base is 7

jim_thompson5910 · Answer
